First Sagittarius A* Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole in the Center of the Milky Way

The Event Horizon Telescope Collaboration

We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A), the Galactic center source associated with a supermassive black hole. These observati…

Bright beacons? ALMA non-detection of a supposedly bright [OI] 63-um line in a redshift-6 dusty galaxy

M. Rybak, L. Lemsom, A. Lundgren +8

We report a non-detection of the [OI] 63-um emission line from the z = 6.03 galaxy G09.83808 using ALMA Band 9 observations, refuting the previously claimed detection with APEX by…

The SEDIGISM survey: first data release and overview of the Galactic structure

F. Schuller, J. S. Urquhart, T. Csengeri +57

The SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium) survey used the APEX telescope to map 84 deg^2 of the Galactic plane between l = -60 deg…

The SEDIGISM survey: Molecular clouds in the inner Galaxy

A. Duarte-Cabral, D. Colombo, J. S. Urquhart +57

We use the 13CO(2-1) emission from the SEDIGISM high-resolution spectral-line survey of the inner Galaxy, to extract the molecular cloud population with a large dynamic range in sp…

APEX-SEPIA660 Early Science: Gas at densities above cm towards OMC-1

A. Hacar, M. R. Hogerheijde, D. Harsono +12

Context. The star formation rates and stellar densities found in young massive clusters suggest that these stellar systems originate from gas at densities n(H) cm$^{-3}…

Prevalence of SED turndown among classical Be stars: Are all Be stars close binaries?

Robert Klement, A. C. Carciofi, T. Rivinius +16

Rapid rotation is a fundamental characteristic of classical Be stars and a crucial property allowing for the formation of their circumstellar disks. Past evolution in a mass and an…
